Four of the World's Best Futurists(未来学家)

Kevin Kelly

In Physics of the Future, he predicts that glasses and contact lenses will be connected to the Internet and cars will become driverless with the power of the GPS system.

David Brin

Science fiction author and scientist, David Brin has received awards. In 1998, he won the Freedom of Speech Award for The Transparence Society.
